Question
What should I check for error 321 on the AMX-4 Series?
Short Answer
1) Check Items 1 and 3 from Error 320 2) Check for 27 VAC at J4-6 & 7 on Rotor Control Board 3) Check for 60 Hz Inverter signal OK signal at J1-5 on the Rotor Control Board 4) If Error 320 occurs after Error 321, there may be a temperature problem on the 60 Hz Inverter

Question
What should I check for error 322 on the AMX-4 Series?
Short Answer
1) Check Battery Charger Board feedback at U123(U77) Pin 5 of CPU Board 2) Check Battery Charger Board feedback and make sure it is going out to the CPU (TP-6 on the Battery Charger Board) 3) Check the ribbon cable from the Battery Charger Board to the CPU Board 4) Batteries may be defective If Voltage Is Really Less than 90 volts 5) Bad Battery Charger Board 6) Loose Battery terminals
